Reasons for high TDS value of reverse osmosis pure water machine

Sep 10, 2020

1. There is an infiltration process when the RO membrane is first watered. During this period, a small amount of residual substances in the production of membrane materials will be dissolved in the water and washed out. If a wet membrane is used, the preservative inside the membrane will also be dissolved in the water and washed out. This process generally takes 1-2 hours, and the TDS of pure water is gradually decreasing. 

2. A small amount of carbon powder and inorganic minerals in the rear activated carbon will be washed out when the water is passed for the first time, resulting in a high TDS. The solution is to fill the pressure bucket with water when making water in the ground. Turn on and off the pure water faucet several times to allow pure water to flush out the impurities in the activated carbon filter. This process takes about 1 hour.
